SPINDLE FOR DOUBLING AND SPINNING.

Specification of Letters Patent.

Patented May 31, 1921.

Application filed February 16, 1920. Serial No. 358,840.

-- To all whom it may concern Be it known that we, JOHN KRAINK and FREDERICK KRAINK, citizens of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Spindles for Doubling and Spinning, of which the following is a specification.

Our invention relates to spinning and doubling spindles of the kind set forth in the patent to G. Kraink, No. 625,039, in which the spool and spindle proper are made to rotate at difierent speeds through the medium of gearing connecting the supporting member for the spool, rotative on such spindle proper, with the latter. The object of the invention is to construct the spindle mechanism so that different numbers of twists to a given length of the thread or yarn may be accomplished at the will of the operator.

Figure 1 of the accompanying drawing shows the improved spindle in side elevation;

Fig. 2 is a verticalsectional view of the part of the spindle having the gearing.

Fig. 3 is a vertical sectional view taken at right angles to Fig. 2 and showing the same part of the spindle;

Fig. 4 is a horizontal sectional view taken just above the flier disk with the spool supporting member removed; and

Fig. 5 presents side and underneath plan views of said member, showing a different size thereof.

The spindle proper a journaled in the bearings b b carries the driving whirl 0. A part of the bearing 5 is a sleeve d which is fixed therein and has affixed to it a bush 6 having an internally threaded portion or screw 6'. On the spindle proper is arranged the fliervdisk 7 which is affixed thereto by means of its hub f, and upstanding from this disk are the flier arms 9 g connected at their upper ends by the yoke h, one of the flier arms being engaged with the traveler i which runs around, with the rotating flier arm, in the suitably supported stationary ring j. j is simply a casing or housing for the gearing, to be described.

A vertical slot is is formed in the spindle proper and on a transverse pin Z therein is journaled a pair of pinions m, n, the former having its teeth spiral-cut and engaged with the screw 6'. The slotted portion of the spindle proper is traversed by another pin or shaft 0 which rotates therein; one end of this pin or shaft is a head 0 and on the other end is a pinion 19, such head and pinion keeping the pinor shaft against endwise movement in its bearing in the spindle proper. The pinion is pinned on the shaft. This pinion is a barrel pinion, that is, it is elongated in the direction of the length of its axis. The pinion projects up through a hole 9 in plate or disk f, and over the head 0 the disk may have another hole 9 to permit access to the head for applying thereto solder or equivalent weight to balance the pinion p and so keep the spindle proper true. Suitably fixed on shaft 0 within slot is is another pinion p in mesh with pinion n.

The spool supporting member consists of a disk 1" on which the spool s rests, the same having a pin t to engage a hole' in the lower head of the spool and form an interlock between the spool and said member, and a gear u, suitably secured to the disk, which is cup-shaped at its under side and has teeth u formed continuously of its rim or edge. Said member is freely penetrated by the spindle proper, though it closely fits the same, and it rests on the hub f of the flier disk f, its teeth u being engaged with the teeth of the barrel disk p.

In Fig. 5 is shown a spool supporting member of a different diameter from that shown in Fig. 2, and in view of this it will be understood that any desired size of such member may be utilized, and that according to such difference in size (to wit, diameter of its toothed portion a) twists in the yarn or thread being spun and wound on the spool in varying numbers to any given length of such yarn will be eifected, the effect of the gearing being to rotate the spool at a different speed from that of the spindle proper and flier the same as in the Kraink patent aforesaid.

It will be understood that in order to substitute one spool supporting member for another it is only necessary to detach the yoke h, which is removably attached to the flier arms, then the spool and finally the spool su. porting member.

aving thus fully described our invention, what We claim is:

1. In combination, a fixed structure having a gear device, a spindle proper journaled upright in said structure, a flier fixed on the spindle proper, a rotary gear device including a barrel pinion and journaled in the spindle proper on an axis transverse thereto, gearing connecting the two gear devices with each other and journaled in the spindle proper, and a spool supporting member" journaled 011 the spindle proper above the barrel pinion and having teeth on the under side thereof in mesh with said barrel pinion. v

2. In combination, a fixed structure having a gear device, a spindle proper j ournaled upright in said structure, a flier fixed on the spindle proper, a rotary gear device including a barrel pinion and a balance-weightdle proper on an axis transverse thereto with the pinion on one side. and said portion on the other side of the spindle proper, gearing connecting the two gear devices with each other and journaled in the spindle proper, and a spool supporting member journaled on the spindle proper above the barrel pinion and having teeth on the under side thereof in mesh with said barrel portion. V

Intestimony whereof we afiix our signa tures.
